Detailed Description

A Delaunay triangulation is created with the input points, no simplification is applied.

Also, the constrain<X>Vertices parameters are ignored. This creation strategy is useful to just triangulate regular grids, where the vertices at the borders are always the same for neighboring tiles.

Member Function Documentation

◆ create()

Polyhedron TinCreation::TinCreationDelaunayStrategy::create	(	const std::vector< Point_3 > &	dataPts,
		const bool &	constrainEasternVertices,
		const bool &	constrainWesternVertices,
		const bool &	constrainNorthernVertices,
		const bool &	constrainSouthernVertices
	)

virtual

Create a TIN from a set of points.

While it does not impose any regularity on the input points, the use of constrain<X>Vertices is restricted to the shape of the convex hull of the input point being an axis-aligned rectangle.

Parameters

dataPts	Input 3D point set
constrainEasternVertices	Flag indicating whether the vertices on the eastern border of the tile should be preserved or not
constrainWesternVertices	Flag indicating whether the vertices on the western border of the tile should be preserved or not
constrainNorthernVertices	Flag indicating whether the vertices on the northern border of the tile should be preserved or not
constrainSouthernVertices	Flag indicating whether the vertices on the southern border of the tile should be preserved or not

Returns

Implements TinCreation::TinCreationStrategy.

◆ setParamsForZoom()

void TinCreation::TinCreationDelaunayStrategy::setParamsForZoom ( const unsigned int & zoom )

inlinevirtual

Adapts the parameters of the algorithm for the desired zoom level.
